The adult insect that has wings and can fly is?

The Indian meal moth is the correct answer because it is the only adult insect among the given options that possesses wings and the ability to fly. This species is known for its distinctive appearance, with members typically having a wingspan that allows them to traverse distances in search of food sources or suitable environments for breeding.

In contrast, the confused flour beetle, granary weevil, and silverfish do not have this ability. The confused flour beetle is a flightless beetle typically found in stored products but lacks wings at maturity. The granary weevil, although it is a beetle, has reduced wings that are not functional for flight; it relies on movement by crawling. The silverfish is another insect that lacks wings entirely, making it incapable of flight. Therefore, the presence of wings and the capacity for flight clearly identify the Indian meal moth as the correct choice in this context.
